As shown in FIG. 2, the STA A may transmit a grant frame 206, e.g., to the STA B.

As shown in FIG. 2, the STA A and/or STA B may set a grant allocation duration 210 to begin at an end of a time period 208 (“grant duration”) indicated by a duration field of the grant frame 206.

As shown in FIG. 2, the Grant duration 208 may be set to end at an end of the duration 202. Accordingly, the allocation duration 210 may begin at the end of the duration 202.

In some demonstrative embodiments, defining the duration field of a grant frame to indicate a time at which an allocated time size indicated in an Allocation duration field of the grant frame may start my not be suitable for some use cases, scenarios, and/or implementations, e.g., as described below.

Referring back to FIG. 1, devices 102 and/or 140 may be configured to use a grant frame to perform dynamic allocation within a Transmit Opportunity (“TxOP” or “TXOP”) or a Service Period (SP), e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate a grant frame during a Contention based Access Period (CBAP).

In some demonstrative embodiments, the grant frame may be transmitted during a TxOP. For example, the grant frame may be transmitted from a TxOP holder station to a TxOP responder station. In one example, device 102 may perform the functionality of the TxOP holder station, and/or device 140 may perform the functionality of the TxOP responder station.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use the grant frame, for example, during a CBAP, for example, to grant an allocation beyond a current TxOP, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use the grant frame, for example, during a CBAP, for example, to grant an allocation within a current TxOP, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate the grant frame during a Service Period (SP). For example, the grant frame may be transmitted from a Source STA of the SP to a destination station of the SP. In one example, device 102 may perform the functionality of the source STA, and/or device 140 may perform the functionality of the destination station.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to use the grant frame, for example, during a SP, for example, to grant an allocation within a current SP, e.g., as described below.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to perform dynamic allocation within a TxOP or a SP, e.g., as described below.

In some demonstrative embodiments, devices 102 and 140 may be configured to reschedule, e.g., relinquish, a remainder of a TXOP or a SP, for example, using a grant frame, e.g., as described below.

In one example, device 102 may be the holder of a TXOP. Controller 124 may be configured to reschedule, e.g., relinquish, a remainder of the TXOP, for example, to another device, e.g., to device 140, for example, if device 102 has no additional data to be transmitted during the TxOP, or for any other reason.

In one example, controller 124 may cause radio 144 to transmit, e.g., to device 140, a grant frame configured to reschedule, e.g., relinquish, at least part of the TxOP, e.g., a remainder of the TxOP, to another device, e.g., to device 140, as described below.

In one example, device 102 may be the source STA of a SP. Controller 124 may be configured to reschedule, e.g., relinquish, a remainder of the SP, for example, to another device, e.g., to device 140, for example, if device 102 has no additional data to be transmitted during the SP, or for any other reason.

In one example, controller 124 may cause radio 114 to transmit, e.g., to device 140, a grant frame configured to reschedule, e.g., relinquish, at least part of the SP, e.g., a remainder of the SP, to another device, e.g., to device 140, as described below.

In some demonstrative embodiments, when rescheduling at least part of the TXOP or the SP, the grant frame may be configured to allocate time within the TxOP or SP, e.g., while not allocating time in addition to the existent TxOP or SP.

In some demonstrative embodiments, the duration field of the grant frame may be set to point to an end of the TxOP or SP.

In some demonstrative embodiments, defining the allocated time of the Allocation Duration field of the grant frame to begin at the end of the time period indicated by the duration field of the grant frame, e.g., as described above, may not enable device 102 to communicate to device 140 that the remainder of the TxOP or SP is to be rescheduled, e.g., if the duration field points to end of the TxOP or SP. Current versions of protocols and/or standards, for example, IEEE 802.11ad-2012 and/or IEEE 802.11REVmc, do not provide a solution for this situation.

In some demonstrative embodiments, setting the duration field to cover the dynamically allocated time, e.g., and not the start of the dynamic allocation, may not provide an efficient solution in some scenarios, use cases and/or implementations, for example, when the allocated time may start at an end of the time presented in the duration field.

In some demonstrative embodiments, devices 102 and 140 may be configured to use a predefined value, e.g., a reserved value, in the Allocation duration field of the grant frame, for example, instead of a value indicating a size of an allocated duration, e.g., as described below.

In some demonstrative embodiments, when using the grant frame during a TXOP, the predefined value, e.g., the reserved value, may be configured to indicate that a remainder of the TxOP is to be rescheduled, for example, from a transmitter of the grant frame to a receiver of the grant frame, for example, if the grant frame is transmitted during the TXOP.

In one example, controller 124 may address the grant frame to device 140, and may set the Allocation duration field of the grant frame to the predefined value, for example, to indicate that a remainder of the TxOP is to be rescheduled, e.g., relinquished, to device 140.

In some demonstrative embodiments, when the allocation is out of the TxOP, the allocation may start at the sum of the value in the Duration field (“duration value”) and the value in the Allocation Duration field (“allocation duration value”), e.g., as described below.

In one example, controller 124 may address the grant frame to device 140, and may set the Allocation duration field of the grant frame to a value other than the predefined value, for example, to indicate an actual size, e.g., in microseconds, of a period to be allocated following the duration indicated by the duration field of the grant frame, e.g., as described below.

In some demonstrative embodiments, when using the grant frame during a SP, the predefined value, e.g., the reserved value, may be configured to indicate that a remainder of the SP is to be rescheduled, for example, from a transmitter of the grant frame to a receiver of the grant frame, for example, if the grant frame is transmitted during the SP.

In one example, controller 124 may address the grant frame to device 140, and may set the Allocation duration field of the grant frame to the predefined value, for example, to indicate that a remainder of the SP is to be rescheduled, e.g., relinquished, to device 140.

Reference is made to FIG. 3, which schematically illustrates a grant frame 300, in accordance with some demonstrative embodiments. For example, the grant frame 300 may be transmitted from a first device, e.g., device 102 (FIG. 1), to a second device, e.g., device 140 (FIG. 1).

As shown in FIG. 3, grant frame 300 may include a duration field 302 (also referred to as “Duration/ID field”), a receive address (RA) field 304, a transmit address (TA) field, 306 and a dynamic allocation information (info) field 308.

In some demonstrative embodiments, the RA field 304 may include, for example, an address, e.g., a MAC address, of a station to receive the grant frame 300, e.g., device 140 (FIG. 1), and the TA field may include, for example, an address, e.g., a MAC address, of a station transmitting the grant frame 300, e.g., device 102 (FIG. 1).

Reference is also made to FIG. 4 is a schematic illustration of a dynamic allocation information field 400, in accordance with some demonstrative embodiments. For example, dynamic allocation information field 400 may perform the functionality of the dynamic allocation info field 308 (FIG. 3).

In some demonstrative embodiments, dynamic allocation field 400 may include an Allocation type field 409, which may be set, for example, to define a channel access mechanism during an allocation to be granted by grant frame 300 (FIG. 3). In one example, Allocation type field 409 may be set to a first value, e.g., to indicate a SP, or to a second value, e.g., to indicate a CBAP.

In some demonstrative embodiments, dynamic allocation information field 400 may include a Source Association Identifier (AID) field 410, which may be set to identify a STA that is to be a source of an allocation, e.g., to be granted by grant frame 300 (FIG. 3).

In some demonstrative embodiments, dynamic allocation information field 400 may include a Destination AID field 412, which may be set to identify a STA that is to be a destination of the allocation, e.g., to be granted by grant frame 300 (FIG. 3).

In some demonstrative embodiments, dynamic allocation information field 400 may include an Allocation duration subfield 402, e.g., as described below.

In some demonstrative embodiments, when an Dynamic Allocation Info subfield, e.g., Dynamic allocation subfield 400, is transmitted within a Grant frame, e.g., grant frame 300 (FIG. 3), the Allocation Duration subfield, e.g., Allocation Duration subfield 402, may be set to contain, for example, a granted duration, for example, of an allocated time, e.g., of a Service Period (SP) allocation or Contention Based Access Period (CBAP) allocation, e.g., in microseconds.

In some demonstrative embodiments, Allocation Duration subfield 402 may be configured to include a duration value, e.g., in microseconds, which may be selected, for example, from a predefined a range of values (“possible values”).

In one example, possible values of Allocation Duration subfield 402 may range, for example, from 0 to 32767, e.g., for a CBAP allocation. In other embodiments, the value of Allocation Duration subfield 402 may be set within any other predefined range of values.

In some demonstrative embodiments, the Allocation Duration field 402 for a CBAP allocation may be limited by a limit of the TxOP, e.g., during which the grant frame is transmitted.

In some demonstrative embodiments, Allocation Duration subfield 402 may be configured to include a predefined value, which may not be in the range of possible values, for example, to indicate that the grant frame 300 (FIG. 3) is to be used to reschedule, e.g., relinquish, a TxOP or a SP, e.g., as described below.

In some demonstrative embodiments, if a value, for example, which is not in the range of possible values, e.g., a value of 32768, is set in the Allocation Duration subfield 402 transmitted within a Grant frame 300 (FIG. 3), then a dynamical allocation may start after, for example, a Short Inter Frame Space (SIFS) after, the sent Grant frame 300 (FIG. 3), or a SIFS after a sent Grant Acknowledge (Ack) frame, e.g., if a Grant Ack Supported field is equal to 1 in a responder's DMG Capabilities element.

In some demonstrative embodiments, if the value of 32768 in the Allocation Duration subfield 402 is transmitted within the Grant frame 300 then, for example, the dynamical allocation may continue, for example, until expiration of the duration presented in the Duration/ID field of the Grant frame, e.g., duration field 302 (FIG. 3) of grant frame 300 (FIG. 3).

In some demonstrative embodiments, a value of “0” in the Allocation Duration subfield 402 transmitted within a Grant frame 300 (FIG. 3) may mean, for example, that the STA can transmit one PPDU followed by any relevant acknowledgment plus one Request to Send (RTS)/DMG Clear to Send (CTS) handshake.

In some demonstrative embodiments, the Allocation Duration subfield 402 of a grant frame, e.g., grant frame 300 (FIG. 3), transmitted in TxOP or a SP, may be set to the predefined value, e.g., the value of 32768, for example, to indicate that the grant frame is to be used to relinquish a remainder of the TxOP or SP, e.g., as described below.

Reference is made to FIG. 5, which schematically illustrates a dynamic allocation of a Transmit Opportunity (TxOP), in accordance with some demonstrative embodiments.

Some demonstrative embodiments are described below with respect to operations and/or communications configured to relinquish a remainder of a TXOP, e.g., as described below with reference to FIG. 5. In other embodiments, one or more of the operations and/or communications may be implemented, for example, to relinquish a remainder of a SP, or any other period or allocation.

As shown in FIG. 5, a first device (STA A), e.g., device 102 (FIG. 1), may be a TxOP holder of a TxOP 501. For example, the STA A may transmit a Request to Send (RTS) frame 502, or any other transmission configured to obtain TxOP 501. The STA B may respond to the RTS 502 with a Clear to Send (CTS) frame 504, or any other frame.

In some demonstrative embodiments, the TxOP 501 may be within a CBAP.

As shown in FIG. 5, STA A may transmit a data frame, e.g., an A-MPDU 506, to STA B, and STA B may respond with a Block Acknowledge (BACK) 508.

As shown in FIG. 5, the STA A may transmit a grant frame 510, e.g., to the STA B.

In some demonstrative embodiments, controller 124 (FIG. 1) may set the predefined value, e.g., the value of 32768, in the Allocation Duration field, e.g., allocation duration field 402 (FIG. 4), of the grant frame 510. The predefined value may be configured, for example, to be outside the range of possible values, e.g., the range 0-32767, which may be used to indicate an allocated duration of a time period, e.g., as described above.

In some demonstrative embodiments, controller 124 (FIG. 1) may set the Allocation duration field 402 (FIG. 4) of Grant frame 510 to the predefined value of 32768, for example, to indicate that the remainder 507 of the TxOP 501, e.g., as indicated in the Duration field 302 (FIG. 3) of the Grant frame 510, is to be reallocated, e.g., relinquished, for example, from STA A to STA B, for example, such that the STA B may become the TXOP holder and the STA A may become the TXOP responder.

For example, as shown in FIG. 5, the STA B may be allowed to transmit a transmission, e.g., an A-MPDU 512, to STA A, and STA A may respond with a BACK 514.

Referring back to FIG. 1, in some demonstrative embodiments, device 102 may transmit a grant frame, e.g., grant frame 300 (FIG. 3), for example, during a CBAP.

In some demonstrative embodiments, the grant frame may include an Allocation duration field, e.g., Allocation duration field 402 (FIG. 4), which may be set to indicate a purpose of the grant frame transmission, e.g., as described below.

In some demonstrative embodiments, when a Dynamic Allocation Info subfield, e.g., the Dynamic Allocation Info subfield 308 (FIG. 3) of frame 300 (FIG. 3), is transmitted within a Grant frame of a CBAP, e.g., grant frame 300 (FIG. 3), the value of the Allocation Duration field, e.g., duration allocation field 402 (FIG. 4), may indicate a purpose of the Grant frame transmission.

In some demonstrative embodiments, two purposes may be possible for the Grant frame transmission, e.g., as follows:

-   a) Beyond current TXOP: in this case, the Allocation Duration field     values range from 0 to 32 767. The value of the Allocation Duration     field plus the Duration field of the Grant frame indicates the time     offset from the PHY-TXEND.indication primitive of the Grant frame     when the STA transmitting the Grant frame will attempt to initiate     access for communication with the STA indicated by the RA field of     the Grant frame. -   b) Within same TXOP: in this case, the Allocation Duration subfield     is set to 32 768.

In one example, device 102 may transmit grant frame 300 (FIG. 3) to grant an allocation after a current TxOP, e.g., as described above. According to this example, device 102 may set the grant frame 300 (FIG. 3) to include the Allocation Duration field 402 (FIG. 4) set to a value within a predefined range of values, e.g., within the range of the values between 0 and 32 767.

According to this example, a beginning of the granted allocation may be determined, for example, based on a sum of the value of the Allocation duration field 402 (FIG. 4) and the value of the duration field 302 (FIG. 3) of the grant frame 300 (FIG. 3). For example, the sum of the value of the Allocation duration field 402 (FIG. 4) and the value of the duration field 302 (FIG. 3) of the grant frame 300 (FIG. 3) may indicate a time offset from a PHY-TXEND.indication primitive of the Grant frame 300 (FIG. 3), when the STA transmitting the Grant frame 300 (FIG. 3), e.g., device 102, is to attempt to initiate access for communication with the STA indicated by the RA field 304 (FIG. 3) of the Grant frame 300 (FIG. 3), e.g., device 140. Additionally or alternatively, for example, the sum of the value of the Allocation duration field 402 (FIG. 4) and the value of the duration field 302 (FIG. 3) of the grant frame 300 (FIG. 3) may indicate a time offset from a PHY-TXEND.indication primitive of the Grant frame 300 (FIG. 3), when the STA transmitting the Grant frame 300 (FIG. 3), e.g., device 102, may be ready to receive a transmission attempt from the STA indicated by the RA field 304 (FIG. 3) of the Grant frame 300 (FIG. 3), e.g., device 140.

In another example, device 102 may transmit grant frame 300 (FIG. 3),e.g., to device 140, for example, to grant an allocation within the same current TxOP, e.g., as described above.

According to this example, device 102 may set the grant frame 300 (FIG. 3) to include the Allocation Duration field 402 (FIG. 4) set to a predefined value, which is not within the predefined range of values, e.g., the value 32 768. According to this example, the predefined value of the Allocation duration field 402 (FIG. 4) may indicate that a remainder of the TxOP is to be relinquished, for example, to device 140, e.g., as described above.

In some demonstrative embodiments, any other additional or alternative purposes may be defined for the grant frame.

In some demonstrative embodiments, device 102 may transmit a grant frame, e.g., grant frame 300 (FIG. 3), for example, during a SP.

In some demonstrative embodiments, when the Dynamic Allocation Info subfield is transmitted within a Grant frame by a source STA of an SP, the Allocation Duration subfield is set to 32768.

In one example, device 102 may perform the functionality of a source STA of an SP. Device 102 may transmit grant frame 300 (FIG. 3) including the Dynamic Allocation Info subfield 308 (FIG. 3) including the Allocation Duration subfield 402 (FIG. 4) set to 32768.

In some demonstrative embodiments, devices 102 and/or 140 may be configured to communicate the grant frame 300 (FIG. 3), for example, to allocate a Grant Period (GP).

In some demonstrative embodiments, during an SP between a source DMG STA, e.g., device 102, and a destination DMG STA, e.g., device 140, the source DMG STA may transmit a Grant frame, e.g., grant frame 300 (FIG. 3), to the destination DMG STA, for example, to relinquish the remainder of the SP to the destination DMG STA.

In some demonstrative embodiments, in the Allocation Info field of the transmitted Grant frame, e.g., Allocation Info field 308 (FIG. 3) of grant frame 300 (FIG. 3), the source DMG STA shall set the source AID field, e.g., source AID field 410 (FIG. 4), to the AID of the destination DMG STA, the destination AID field, e.g., destination AID field 412 (FIG. 4), to the AID of the source DMG STA, the Allocation Type field, e.g., Allocation Type field 409 (FIG. 4), set to indicate SP, and the Duration field, e.g., duration field 302 (FIG. 3), set to the time remaining in the SP minus TXTIME (Grant frame) minus a Short Inter Frame Space (SIFS) Time.

In some demonstrative embodiments, the Allocation Duration field, e.g., Allocation Duration field 402 (FIG. 4), in the Grant frame, e.g., grant frame 300 (FIG. 3), shall be set as defined above, e.g., to the value 32768.

In some demonstrative embodiments, upon transmission of the Grant frame with the Beamforming Training field equal to 0, for the remainder of the SP the roles of source DMG STA and destination DMG STA are swapped between the STAs.

In some demonstrative embodiments, during a TxOP between a TXOP holder, e.g., device 102, and a TXOP responder, e.g., device 140, the TXOP holder may transmit a Grant frame, e.g., grant frame 300 (FIG. 3), to the TXOP responder to relinquish the remainder of the TXOP to the TXOP responder.

In some demonstrative embodiments, in the transmitted Grant frame, e.g., grant frame 300 (FIG. 3), the TXOP holder shall set a source AID field, e.g., source AID field 410 (FIG. 4), to the AID of the TXOP responder, the destination AID field, e.g., destination AID field 412 (FIG. 4), to the AID of the TXOP holder, the Allocation Type field, e.g., Allocation type field 409 (FIG. 4), set to indicate CBAP, and the Duration field, e.g., duration field 302 (FIG. 3), set to the time remaining in the TXOP minus TXTIME (Grant frame) minus a Short Inter Frame Space (SIFS) Time.

In some demonstrative embodiments, the Allocation Duration field, e.g., allocation duration field 402 (FIG. 4), in the Grant frame shall be set, for example, as described above. For example, the Allocation Duration field 402 (FIG. 4) in the Grant frame 300 (FIG. 3) may be set to the predefined value, e.g., 32 768, for example, to indicate the grant frame 300 (FIG. 3) is to relinquish the remainder of the TxOP to the TxOP responder, e.g., as described above.

In some demonstrative embodiments, upon transmission of the Grant frame with a Beamforming Training field equal to 0, for the remainder the TxOP the roles of TXOP holder and TXOP responder are swapped between the STAs.

In some demonstrative embodiments, controller 124 may cause a first wireless station implemented by device 102 to generate a grant frame, e.g., grant frame 300 (FIG. 3), including a duration field, e.g., duration field 302 (FIG. 3), and a dynamic allocation information field, e.g., dynamic allocation info field 400 (FIG. 4), including an allocation duration subfield, e.g., allocation duration subfield 402 (FIG. 4), being set to a value within a predefined range of values, e.g., the range 0-32767, for example, when the grant frame is to grant to a second wireless station, e.g., device 140, a period after a TxOP, e.g., as described above.

In some demonstrative embodiments, controller 124 may cause the first wireless station implemented by device 102 to generate the grant frame including the allocation duration subfield, e.g., allocation duration subfield 402 (FIG. 4), being set to a predefined value, e.g., the value 32768, which is not within the predefined range of values, for example, when the grant frame is to grant to the second wireless station, e.g., device 140, a period within the TxOP, e.g., as described above.

In some demonstrative embodiments, controller 124 may causer the first wireless station to transmit the grant frame during the TxOP, e.g., via radio 114.

In some demonstrative embodiments, controller 124 may cause the first wireless station to transmit the grant frame in a CBAP, e.g., as described above.

In some demonstrative embodiments, controller 124 may cause the first wireless station to operate as a holder of the TxOP, e.g., as described above.

For example, controller 124 may cause device 102 to transmit the grant frame 300 (FIG. 3) including the allocation duration subfield 402 (FIG. 4) set to the predefined value, e.g., 32628, for example, to indicate that a remainder of the TxOP is to be relinquished from the TxOP holder to a TxOP responder, e.g., device 140.

In some demonstrative embodiments, controller 124 may cause the first wireless station to set a value of the duration field 302 (FIG. 3) to a result of subtracting from a time remaining in the TxOP a transmit time of the grant frame 300 (FIG. 3) and a Short Inter Frame Space (SIFS) time, e.g., as described above.

In some demonstrative embodiments, controller 124 may cause the first wireless station to set the allocation duration subfield to the value within the predefined range of values, e.g., to a value within the range 0-32627, to indicate that the first wireless station is to attempt to initiate access to communicate with the second wireless station, e.g., device 140, at a time which is based on a sum of the value of the allocation duration subfield 402 (FIG. 4) and a value of the duration field 302 (FIG. 3), e.g., as described above.

In some demonstrative embodiments, controller 154 may cause the second wireless station, e.g., which may be implemented by device 140, to process a reception of the grant frame from the first wireless station. For example, controller 154 may cause radio 144 and/or message processor 158 to process the reception of the grant frame 300 (FIG. 3) including the dynamic allocation subfield 402 (FIG. 4) set to the value within the predefined range of values, when the grant frame 300 (FIG. 3) is to grant the period after the TxOP, or including the allocation duration subfield 402 (FIG. 4) set to the predefined value which is not within the predefined range of values, when the grant frame 300 (FIG. 3) is to grant the period within the TxOP, e.g., as described above.

In some demonstrative embodiments, controller 154 may cause the second wireless station, e.g., which may be implemented by device 140, to, based on the allocation duration subfield, process a communication in the period after the TxOP or in the period within the TxOP, e.g., as described above.

In some demonstrative embodiments, controller 124 may cause a first wireless station implemented by device 102 to generate a grant frame, e.g., grant frame 300 (FIG. 3), including a duration field, e.g., duration field 302 (FIG. 3), and a dynamic allocation information field, e.g., dynamic allocation info field 400 (FIG. 4), including an allocation duration subfield, e.g., allocation duration subfield 402 (FIG. 4), being set to a predefined value, e.g., the value 32768, and the duration field, e.g., duration field 302 (FIG. 3), being set to a result of subtracting from a time remaining in a SP a transmit time of the grant frame 300 (FIG. 3) and a SIFS, for example, the difference between the time remaining in the SP and the sum of the transmit time of the grant frame 300 (FIG. 3) and a SIFS, e.g., as described above.

In some demonstrative embodiments, controller 124 may cause the first wireless station to transmit the grant frame during the SP, e.g., via radio 114.

In some demonstrative embodiments, controller 124 may cause the first wireless station to operate as a source station of the SP, and to relinquish a remainder of the SP from the source station to a destination station of the SP, e.g., a second wireless station implemented by device 140.

In some demonstrative embodiments, controller 154 may cause the second wireless station, e.g., which may be implemented by device 140, to process a reception of the grant frame from the first wireless station. For example, controller 154 may cause radio 144 and/or message processor 158 to process the reception of the grant frame 300 (FIG. 3) including the dynamic allocation subfield 402 (FIG. 4) set to the predefined value, e.g., 32768, for example, during the SP, e.g., as described above.

In some demonstrative embodiments, controller 154 may cause the second wireless station, e.g., which may be implemented by device 140, to perform the role of the source station of the SP for a remainder of the SP, e.g., as described above.

Reference is made to FIG. 6, which schematically illustrates a method of dynamic allocation using a grant frame, in accordance with some demonstrative embodiments. For example, one or more of the operations of the method of FIG. 6 may be performed by one or more elements of a system, e.g., system 100 (FIG. 1), for example, one or more wireless devices, e.g., device 102 (FIG. 1) and/or device 140 (FIG. 1), a controller, e.g., controller 124 (FIG. 1) and/or controller 154 (FIG. 1), a radio, e.g., radio 114 (FIG. 1) and/or radio 144 (FIG. 1), and/or a message processor, e.g., message processor 128 (FIG. 1) and/or message processor 158 (FIG. 1).
